Happy May um sixth!
This is my jam. Aside from a few wacky musical choices (the TECHNO ROCK that blemishes the otherwise gorgeous rock scaling attack?), it's pretty close to perfect.
The animation is crisp, kinetic, and pretty. The show had a weird arc, it started beautiful, got somehow better, then turned to muddy shit by the Netflix episodes. (I haven't seen much of Rebels, and Gumby Vader isn't convincing me to watch more.) This manages to be a more ~cinematic~ version of the former. Nice to have time for sweeping pans during group interactions and long establishing shots of Republic star cruisers.
Still, even Filoni at his best -- which he certainly is here -- can never be much more than cartoon EU. The kindest thing you can say about this is that it looks like a really wizard video game version of the last third of AotC and first two thirds of Sith.
